Neo gene ter res trial sed i men tary en vi ron ments of the Orava-Nowy Targ Basin: a case study of the Oravica River sec tion near Èimhová, Slovakia. Geo log i cal Quar terly, 59 (1): 21-34, doi: 10.7306/gq.1209The Orava-Nowy Targ Ba sin is an intramontane de pres sion lo cated at the bor der of the In ner and Outer Carpathians. It is filled mostly with fine-grained ter res trial and fresh-wa ter de pos its of Neo gene and Qua ter nary age, which re cord the structural evo lu tion and de nu da tion pro cesses of the sur round ing re gions: Orava, Podhale, and the Tatra Mts. The Orava-Nowy Targ Ba sin fill was stud ied in the Oravica River sec tion, which re veals 90 m thick Neo gene de pos its and al lows ob ser va tion of their lat eral di ver sity. Fif teen lithofacies and seven fa cies as so ci a tions dis tin guished here doc u ment the depositional evolu tion of the ba sin fill, start ing from hill-slope de bris flow through silt turbidite-bear ing lake, to flood-dom i nated flu vial plain, swamp and al lu vial fan de pos its, as well as a pyroclastic event. The palaeorelief was low dur ing de po si tion and the Orava-Nowy Targ Ba sin could have spread sig nif i cantly more to the south.

Tectono-sedimentary analysis using the anisotropy of magnetic susceptibility: a study of the terrestrial and freshwater Neogene of the Orava Basin

“…The dominant siliciclastic basin infill has been probably derived from older eroded units exposed in the vicinity of the basin (Birkenmajer 1954;Watycha 1976a;Tokarski et al 2012). The deposition of conglomerates, sandstones, clayey siltstones, claystones, and coals took place in terrestrial and freshwater environments: alluvial fans, rivers, flood plains, lakes and swamps (Watycha 1976a;Birkenmajer 1978;Kukulak 1998;Łoziński et al 2015). The sedimentary bodies of deposits are laterally and vertically restricted, and strongly depend on their paleotopographic position.…”

“…Lacustrine deposits represent episodic lakes and no basin-scale reservoir has been recorded during the basin's evolution (Watycha 1976a;Łoziński et al 2015). The sedimentary environment could have been disrupted by volcanic ashfall events resulting in tuffite deposition (Beleš 1974;Sikora & Wieser 1974;Kołcon & Wagner 1991;Łoziński et al 2015). The topmost deposits of the Quaternary age (Watycha 1976a;Baumgart-Kotarba et al 1996) lie often discordantly above older deposits.…”

“…The abundant plant vegetation within the wet areas favoured preservation of organic matter and initiated brown coal formation (e.g., Polášek 1959;Oszast & Stuchlik 1977;Kołcon & Wagner 1991). Lacustrine deposits represent episodic lakes and no basin-scale reservoir has been recorded during the basin's evolution (Watycha 1976a;Łoziński et al 2015). The sedimentary environment could have been disrupted by volcanic ashfall events resulting in tuffite deposition (Beleš 1974;Sikora & Wieser 1974;Kołcon & Wagner 1991;Łoziński et al 2015).…”

Landslides on river banks in the western part of Podhale (Central Carpathians, Poland)

“…In geo log i cal terms the land slides formed at the con tact of the sed i ments fill ing the Orava-Nowy Targ De pres sion with the Podhale Synclinorium (com pris ing Oligocene to Early Mio cene sand stones and shales) and the rocks of the Pieniny Klippen Belt (Watycha, 1959(Watycha, , 1976Mastella, 1975;Mastella and Rybak-Ostrowska, 2012;£oziñski et al, 2015). In Neo gene and Qua ter nary times the Orava De pres sion was the main site of sed i ment de po si tion by the rivers drain ing the West ern Tatra Moun tains (Czarny Dunajec River) and the Guba³ówka Foothills (Cichy, Bystry and Czerwony streams).…”
